I'm sorry to see Faris go. I understand why we couldn't keep him though. I hope he's brought back if anybody is hurt.
I wish he could be put on the practice squad but I think thats only for 1 and 2nd year players.

I figure Havner, Ortega, Lefotu, McCune and either Harris or Espy will go to the practice squad.

NFLPA website wrote:Beginning with the 2004 NFL regular season, the League may elect to establish practice squads not to exceed eight players per Club. See Article XXXIV, Sec. 1. The League's election in any one season shall not determine or affect its election in any subsequent season.
